Introducing the Mixed Domain Oscilloscope

Introducing the world’s first and only oscilloscope with a built-in spectrum analyzer. For the first time ever, you can capture time-correlated analog, digital, and RF signals for a complete system view of your device. See both the time and frequency domain in a single glance. View the RF spectrum at any point in time to see how it changes over time or with device state. Solve the most complicated design issues, quickly and efficiently, with an oscilloscope as integrated as your design.

Based on the industry-standard MSO4000B Oscilloscope Series, you can now use your tool of choice, the oscilloscope, to look at the frequency domain rather than having to find and re-learn a spectrum analyzer. However, the power of the MDO goes well beyond simply observing the frequency domain as you would on a spectrum analyzer. The real power is in its ability to correlate events in the frequency domain with the time domain phenomena that caused them.

When both the RF channel and any analog or digital channels are on, the oscilloscope display is split into two views. The upper half of the display is a traditional oscilloscope view of the Time Domain. The lower half of the display is a Frequency Domain view of the RF input. Note that the Frequency Domain view is not simply an FFT of the analog or digital channels in the instrument, but is the spectrum acquired from the RF input.

The spectrum shown in the Frequency Domain view is taken from the period of time indicated by the short orange bar in the time domain view – known as the Spectrum Time. With the MDO4000 Series, Spectrum Time can be moved through the acquisition to investigate how the RF spectrum changes over time. And this can be done while the oscilloscope is live and running or on a stopped acquisition.


The upper half of the MDO4000 Series display shows the Time Domain view of the analog and digital channels, while the lower half shows the Frequency Domain view of the RF channel. The orange bar – Spectrum Time – shows the period of time used to calculate the RF spectrum.

Figures 1 through 4 show a simple everyday application – tuning of a VCO/PLL. This application illustrates the powerful connection between the time domain and the frequency domain that the MDO4000 Series provides. With its wide capture bandwidth and ability to move Spectrum Time throughout the acquisition, this single capture includes the same spectral content as approximately 1,500 unique test setups and acquisitions on a traditional spectrum analyzer. For the first time ever, correlating events, observing interactions, or measuring timing latencies between the two domains is exceptionally easy, giving you quick insight to your design’s operation.


Time and Frequency Domain view showing the turn-on of a VCO/PLL. Channel 1 (yellow) is probing a control signal that enables the VCO. Channel 2 (cyan) is probing the PLL voltage. The SPI bus which is programming the VCO/PLL with the desired frequency is probed with three digital channels and automatically decoded. Notice Spectrum Time is placed after the VCO was enabled and coincident with the command on the SPI bus telling the VCO/PLL the desired frequency.

Spectrum Time is moved about 60 µs to the right. At this point, the spectrum shows that the VCO/PLL is in the process of tuning to the correct frequency (2.400 GHz). It has made it up to 2.3168 GHz.

Spectrum Time is moved another 120 µs to the right. At this point the spectrum shows that the VCO/PLL has actually overshot the correct frequency and gone all the way to 2.4164 GHz.

The VCO/PLL eventually settles on the correct 2.400 GHz frequency about 340 µs after the VCO was enabled.

Visualizing Changes in Your RF Signal

The orange waveform in the Time Domain view is the frequency vs. time trace derived from the RF input signal. Notice that Spectrum Time is positioned during a transition from the highest frequency to the lowest frequency, so the energy is spread across a number of frequencies. With the frequency vs. time trace, you can easily see the different frequency hops, simplifying characterization of how the device switches between frequencies.

The time domain graticule on the MDO4000 Series display provides support for three RF time domain traces that are derived from the underlying I and Q data of the RF input including:

  • Amplitude – The instantaneous amplitude of the RF input vs. time
  • Frequency – The instantaneous frequency of the RF input, relative to the center frequency vs. time
  • Phase – The instantaneous phase of the RF input, relative to the center frequency vs. time

Each of these traces may be turned on and off independently, and all three may be displayed simultaneously. RF time domain traces make it easy to understand what’s happening with a time-varying RF signal.

Advanced Triggering

In order to deal with the time-varying nature of modern RF applications, the MDO4000 Series provides a triggered acquisition system that is fully integrated with the RF, analog, and digital channels. This means that a single trigger event coordinates acquisition across all channels, allowing you to capture a spectrum at the precise point in time where an interesting time domain event is occurring. A comprehensive set of time domain triggers are available, including Edge, Sequence, Pulse Width, Timeout, Runt, Logic, Setup/Hold Violation, Rise/Fall Time, Video, and a variety of parallel and serial bus packet triggers. In addition, you can trigger on the power level of the RF input. For example, you can trigger on your RF transmitter turning on.

The optional MDO4TRIG application module provides advanced RF triggering. This module enables the RF input power level to be used as a source for Sequence, Pulse Width, Timeout, Runt, and Logic trigger types. For example, you can trigger on a RF pulse of a specific length or use the RF channel as an input to a logic trigger, enabling the oscilloscope to trigger only when the RF is on while other signals are active.

Fast and Accurate Spectral Analysis

MDO4000 Frequency Domain display.

Key spectral parameters are adjusted quickly with the dedicated front-panel menus and keypad.

When using the RF input by itself, the MDO4000 Series display becomes a full-screen Frequency Domain view.

Key spectral parameters such as Center Frequency, Span, Reference Level, and Resolution Bandwidth are all adjusted quickly and easily using the dedicated front-panel menus and keypad.

Intelligent, Efficient Marker

Automated peak markers identify critical information at a glance. As shown here, the five highest amplitude peaks that meet the threshold and excursion criteria are automatically marked.

In a traditional spectrum analyzer, it can be a very tedious task to turn on and place enough markers to identify all your peaks of interest. The MDO4000 Series makes this process far more efficient by automatically placing markers on peaks that indicate both the frequency and the amplitude of each peak. The criteria used to determine what a peak is can be adjusted by the user.

The highest amplitude peak is referred to as the reference marker and is shown in red. Marker readouts can be switched between Absolute and Delta readouts. When Delta is selected, marker readouts show each peak’s delta frequency and delta amplitude from the reference marker.

Two manual markers are also available for measuring non-peak portions of the spectrum. When enabled, the reference marker is attached to one of the manual markers, enabling delta measurements from anywhere in the spectrum. In addition to frequency and amplitude, manual marker readouts also include noise density and phase noise readouts depending on whether Absolute or Delta readouts are selected. A “Reference Marker to Center” function instantly moves the frequency indicated by the reference marker to center frequency.

Spectrogram

Spectrogram display illustrates slowly moving RF phenomena. As shown here, a signal that has multiple peaks is being monitored. As the peaks change in both frequency and amplitude over time, the changes are easily seen in the Spectrogram display.

The MDO4000 Series includes a spectrogram display which is ideal for monitoring slowly changing RF phenomena. The x-axis represents frequency, just like a typical spectrum display. However, the y-axis represents time, and color is used to indicate amplitude.

Spectrogram slices are generated by taking each spectrum and “flipping it up on its edge” so that it’s one pixel row tall, and then assigning colors to each pixel based on the amplitude at that frequency. Cold colors (blue, green) are low amplitude and hotter colors (yellow, red) are higher amplitude. Each new acquisition adds another slice at the bottom of the spectrogram and the history moves up one row. When acquisitions are stopped, you can scroll back through the spectrogram to look at any individual spectrum slice.

Triggered vs. Free Run Operation

When both the time and frequency domains are displayed, the spectrum shown is always triggered by the system trigger event and is time correlated with the active time-domain traces. However, when only the frequency domain is displayed, the RF input can be set to Free Run. This is useful when the frequency domain data is continuous and unrelated to events occurring in the time domain.

Ultra-wide Capture Bandwidth

Spectral display of a bursted communication both into a device through Zigbee at 900 MHz and out of the device through Bluetooth at 2.4 GHz, captured with a single acquisition.

Today’s wireless communications vary significantly with time, using sophisticated digital modulation schemes and, often, transmission techniques that involve bursting the output. These modulation schemes can have very wide bandwidth as well. Traditional swept or stepped spectrum analyzers are ill equipped to view these types of signals as they are only able to look at a small portion of the spectrum at any one time.

The amount of spectrum acquired in one acquisition is called the capture bandwidth. Traditional spectrum analyzers sweep or step the capture bandwidth through the desired span to build the requested image. As a result, while the spectrum analyzer is acquiring one portion of the spectrum, the event you care about may be happening in another portion of the spectrum. Most spectrum analyzers on the market today have 10 MHz capture bandwidths, sometimes with expensive options to extend that to 20, 40, or even 140 MHz in some cases.

In order to address the bandwidth requirements of modern RF, the MDO4000 Series provides ≥1 GHz of capture bandwidth. At span settings of 1 GHz and below, there is no requirement to sweep the display. The spectrum is generated from a single acquisition, thus guaranteeing you’ll see the events you’re looking for in the frequency domain.

Spectrum Traces

Normal, Average, Max Hold, and Min Hold spectrum traces.

The MDO4000 Series offers four different traces or views of the RF input including Normal, Average, Max Hold, and Min Hold. You can set the detection method used for each trace type independently or you can leave the oscilloscope in the default Auto mode that sets the detection type optimally for the current configuration. Detection types include +Peak, –Peak, Average, and Sample.

RF Measurements


Automated Channel Power measurement.

The MDO4000 Series includes three automated RF measurements – Channel Power, Adjacent Channel Power Ratio, and Occupied Bandwidth. When one of these RF measurements is activated, the oscilloscope automatically turns on the Average spectrum trace and sets the detection method to Average for optimal measurement results.

RF Probing

The optional TPA-N-VPI adapter enables any active, 50 Ω TekVPI probe to be connected to the RF input.

Signal input methods on spectrum analyzers are typically limited to cabled connections or antennas. But with the optional TPA-N-VPI adapter, any active, 50 Ω TekVPI probe can be used with the RF input on the MDO4000 Series. This enables additional flexibility when hunting for noise sources and enables easier spectral analysis by using true signal browsing on an RF input.
